Product Introduction

This anodized aluminum channel uses silicone gel rather than polyurethane. The referenced gel family supports an approximately -50 to 204 C useful temperature range and forms a self-healing fluid interface around a ceiling or housing knife edge. The formulation suits terminal HEPA and ULPA frames needing repeated room-side changes, although silicone-sensitive processes should use the dedicated silicone-free urethane alternative.

Key Features

Wide thermal flexibility

Silicone gel remains compliant across a broader temperature range than many conventional foam gaskets.

Repeatable edge entry

The fluid seal closes around the knife edge after normal withdrawal and reinsertion.

Low-outgassing option

Selected silicone formulations support cleanroom terminal service where emission control is specified.

Applications

For pharmaceutical, healthcare and general cleanroom terminal filters requiring a reusable knife-edge gel seal over a broad operating range.

Solutions for Your Application

Silicone species are restricted near a sensitive coating or semiconductor process.Use the silicone-free urethane channel after confirming the process contamination specification.

Repeated knife-edge entry tears or contaminates the gel surface.Inspect the complete trough during every change and replace the filter when the gel no longer closes cleanly.

Available Options

Specify silicone formulation, channel geometry, filter grade, frame size, knife-edge height, temperature range and outgassing requirement.
